Abstract
The invention belongs to airborne radome design field, and in particular to a kind of PMI foams strengthen antenna house.The structure of thin-wall construction antenna house is simple, electrical property is preferable, but mechanical performance index is general.The PMI foams of the present invention strengthen antenna house, including outside thin-wall radome and internal PMI foams.The problem of thin-wall construction antenna house mechanical property is general is can solve the problem that, while and can meets the electrical performance indexes of antenna house.The foam-filled reinforcements of PMI are used in thin-wall radome, the rigidity of thin-wall construction antenna house can be strengthened and intensity and meet electrical performance indexes.
Description
Technical field
The invention belongs to airborne radome design field, and in particular to a kind of PMI foams strengthen antenna house.
Background technology
Modern opportunity of combat develops the performance requirement more and more higher to airborne radome, and wherein requirement on electric performance is mainly reflected in frequency
Band is more and more wider, wave transmission rate more and more higher, and the antenna house of broadband and high wave transmission rate typically uses thin-wall construction or sandwich construction.
The structure of thin-wall construction antenna house is simple, electrical property is preferable, but mechanical performance index is general；The electrical property of multiple-layer sandwich radome
Preferably, mechanical performance index is preferable, but complicated is not readily used for small volume and the larger antenna house of curvature.
The content of the invention
The present invention is directed to the problem of thin-wall construction antenna house mechanical property is general, and designing a kind of PMI, (polymethyl acyl is sub-
Amine) foam strengthen antenna cover structure.The mechanical index of thin-wall construction antenna house is improved, simultaneously because PMI foams have preferably
Dielectric properties, its electrical property can also meet index request.
The PMI foams of the present invention strengthen antenna house, including outside thin-wall radome and internal PMI foams, and PMI is poly-
Methacrylimide.
The PMI foams are filled into the inner chamber of thin-wall radome, and thin-wall radome is strengthened.Or the PMI
Foam is bonded to the inner chamber of thin-wall radome, and thin-wall radome is strengthened.
The PMI foam insides also have the cavity of installation antenna.
The PMI foams of the present invention strengthen antenna house, can solve the problem that the problem of thin-wall construction antenna house mechanical property is general, together
When and can meet the electrical performance indexes of antenna house.PMI foams have excellent dielectric properties, are compared in current all foamed materials
Intensity and specific stiffness highest foam, its resistance to elevated temperatures can bear 190 DEG C of solidification temperature.
Brief description of the drawings
Fig. 1 is the longitudinal sectional view that PMI foams of the present invention strengthen antenna house.
Embodiment
Such as Fig. 1, PMI foams 2 are bonded inside the thin-wall radome 1 that shaping finishes, day is reserved in the structure of PMI foams 2
The installation cavity of line.
PMI foams strengthen antenna house, have both added the rigidity and intensity of thin-wall radome, and meet antenna house simultaneously
Electrical performance indexes requirement.It is applied successfully on certain type product and can apply to the product of follow-up similar structures.
